Description

[Detailed explanation of the idea] Industrial applications This proposal concerns a tool for binding PC plate reinforcing bars.

Conventional technology PC boards (precast concrete boards) are widely used as exterior wall materials for buildings, but they are made by inserting reinforcing steel bars inside the concrete board and assembling the upper and lower parts like a net. It's on.

Problems that the invention aims to solve: However, since various forces are applied to the reinforcing bars, metal fittings are made to keep the upper and lower reinforcing bars from being separated to keep them apart. Furthermore, since this fastening fitting is usually a round iron bar, it is time-consuming and troublesome to bend it using a hammer, pliers, etc. in order to wrap it around the reinforcing bar.

Means to Solve the Problems Taking these points into consideration, this proposal provides a tool for binding metal fittings used in such PC board reinforcing cores, and the tool is simple in structure and convenient to handle, and is based on the principle of leverage. This was applied to bend an iron bar without using much force. That is, the binding tool according to the present invention has two parts 1c and 1d that sandwich a cut groove 1b and a hook part 1a whose tip is curved to form the beak shape of an ohm, and which are integrated with the hook part 1a.
and a rear end portion 1e formed by extending the two portions 1c and 1d, and use this to attach a fitting made of a J-shaped round bar 3 to reinforcing reinforcing bars for a pair of PC boards. It was designed to bind together.

Function: By providing a tool for working on the metal fittings that bind the upper and lower reinforcing bars of the reinforcement reinforcing bars for PC boards, this project speeds up the work, is convenient to carry, is easy to handle, and has a great utility model effect. It is.

Embodiment Fig. 1 a is a side view of the PC plate reinforcing bar binding tool according to the present invention, Fig. 1 b is a top view of the same, and Fig. 2 a, b, and c show upper reinforcing bars 2a and lower reinforcing bars 2b connected by J-shaped round bar 3. It is a simplified diagram showing the progress of binding. In the figure, 1 is a reinforcing bar binding tool according to the present invention, and 2a and 2b are PC
Upper reinforcing bars 2a and lower reinforcing bars 2b are shown as reinforcement reinforcing bars for the plate. 3 is a J-shaped round bar that is a metal fitting for binding reinforcing bars. In addition, in the tool 1, 1a is a beak-like hook portion 1b of an ohm whose tip can be curved, and grooves 1c and 1d are used.
are two limbs sandwiching the cut groove 1b, and the tips thereof become the hooking part 1a. 1e is one rear end formed by extending the two limbs 1c and 1d, and 1f is the edge of the cut groove 1b.

Figures 2a, b, and c are simplified diagrams showing the process of wrapping the J-shaped round bar 3 around the upper reinforcing bar 2a and the lower reinforcing bar 2b using the tool 1 according to the present invention, and when using the tool according to the present invention. In the state shown in Figure 1a, that is, Figure 2a, wrap the J-shaped round bar 3 around the lower reinforcing bar 2b, and then attach the ohm-shaped hook part 1a of the tool 1 to the upper reinforcing bar 2a.
When the straight part of the J-shaped round bar 3 is held in the cut groove 1b of the two limbs and the tool is turned counterclockwise, the J-shaped round bar 3 is pressed by the edge 1f of the cut groove 1b. The state shown in Figure 2b is changed to the state shown in Figure 2C using the principle of leverage, so no force is required, so the bending is completed into an O-shape, and the J-shaped round bar 3 is wrapped around the upper and lower reinforcing bars 2a and 2b, and the force that tries to separate it is applied. The distance can be maintained even if In actual use, the inside of the cut groove 1b is 2 to 15
They are provided in parallel with a width of mm, and the beak-shaped curved part of the ohm preferably has an inner radius of about 3 to 20 mm.

Effects of the invention In this way, the upper and lower reinforcing bars 2 are tied together with the J-shaped round bar 3 using an easy-to-handle binding tool.
Wrap it around a and 2b to maintain a gap so that it does not separate, and use a lever tool to easily and reliably bend it without much force.

[Brief explanation of the drawing]

Figures 1a and 1b are side and top views of the binding tool according to the present invention, and Figures 2a, b, and c are simplified diagrams showing the process of binding the upper reinforcing bar 2a and the lower reinforcing bar 2b with the J-shaped round bar 3. It is. In the figure, 1 is the tool, 1a is the beak-like hook of the ohm, 1b is the kerf, 1c and 1d are the two limbs, 1e is the rear end, 1f is the edge of the kerf 1b, 2a and 2b are
Reinforcing reinforcing bars for the PC board, 3 is a round bar for binding reinforcing bars.
